toString method

@override String toString()

A string representation of this object.

Some classes have a default textual representation, often paired with a static parse function (like int.parse). These classes will provide the textual representation as their string representation.

Other classes have no meaningful textual representation that a program will care about. Such classes will typically override toString to provide useful information when inspecting the object, mainly for debugging or logging.

Implementation

@override
String toString() {
  final buffer = StringBuffer()
    // ignore: no_runtimeType_toString
    ..write(runtimeType)
    ..write(': ')
    ..write(description);

  if (message != null) {
    buffer
      ..write(' (')
      ..write(message)
      ..write(')');
  }

  return buffer.toString();
}
